The value 001 is the physical LINE interface address of the FEP. The second parameter specifies whether half- or full-duplex data transfer within the FEP is used. It also effects the DUPLEX parameter: If FULL is specified here, DUPLEX defaults to FULL and attempts to modify this characteristic are ignored.

DUPLEX

HALF

This parameter specifies whether the communication line and modem constitute a half-duplex or full-duplex facility. If HALF is specified, the RTS modem signal is activated only when sending data. If FULL is specified, RTS always remains active. Refer to the ADDRESS parameter in this table.

NRZI

YES

Encoding for this line; options are NRZ or NRZI.

RETRIES

(6,5,3)

Number of retries when REPLYTO expires. Entry options: (m, t, n) where m = number of retries, t = pause in seconds between retry cycles, and n = number of retry cycles to repeat. This example would retry six times-pausing the value of the REPLYTO between each RETRY (two seconds per Table: FEP SDLC Configuration Sample GROUP Parameter Listing and Definitions), pause five seconds, and repeat this sequence three times for a total of 63 seconds. At the end of this period, the session is terminated.

PAUSE

2

The delay time in milliseconds between poll cycles. The cycle extends from the time NCP polls the first entry in the service order table to the moment polling next begins at the same entry. During this pause, any data available to send to the end station is sent. If end stations have data to send when polled and the time to send the data extends beyond the PAUSE parameter, the next poll cycle begins immediately.

C2

Specifies the cluster controller SDLC address. It is the same address that you configure on the router's serial line interface. It also represents the PU address of the controller. In multipoint environments, multiple SDLC addresses may be specified on a single serial interface.
